Boston Bombing Suspect Hospitalized Under Police Guard

WATERTOWN, Mass. (April 20, 2013)—The 19-year-old college student wanted in the Boston Marathon bombings was hospitalized in serious condition under police guard Saturday after a manhunt that left the city virtually paralyzed and his older brother, who was his accomplice, dead.

Dzhokhar Tsarnaev was captured Friday night after he was found hiding in a boat stored in a Watertown, Mass., neighborhood.

He suffered a gunshot wound.

His brother, 26-year-old Tamerlan, was killed Friday in a furious attempt to escape police.

The brothers are suspects in Monday's marathon bombings, which killed three people and wounded more than 180 others.

The men are also suspected of killing a Massachusetts Institute of Technology police officer in his vehicle late Thursday.

Authorities in Boston had suspended all mass transit and warned close to 1 million people in the entire city and some of its suburbs to stay indoors as the hunt for the remaining suspect went on.

The suspects were identified as brothers from the Russian region near Chechnya, which has been plagued by an Islamic insurgency stemming from separatist wars.

The suspects' clashes with police began only a few hours after the FBI released photos and videos of the two young men, who were seen carrying backpacks as they mingled among revelers at Monday's Boston Marathon.

The bombings on Monday killed three people and wounded more than 180 others, and authorities revealed the images to enlist the public's help finding the suspects.

Transportation to and from the Boston area was virtually shut down Friday morning, except for air travel, as planes continued to take off and land at Logan International Airport.

Amtrak stopped trains about an hour south of the city in Providence, R.I.

The Massachusetts Bay Transportation Authority, which operates commuter trains into Boston as well as the city's subway and the city's buses suspended all operations.

JetBlue, the largest airline in Boston, was allowing anybody scheduled to fly to or from Boston to change their tickets for free.

Megabus canceled at least 18 buses between Boston and New York, New Haven, Conn., Hartford, Conn., Burlington, Vt. and Philadelphia.

The slain MIT officer was identified as Sean Collier, 26.

He had worked at the Massachusetts Institute of Technology for about a year, but was already popular with his colleagues in the campus police department, as well as with students, often joining them on hiking and skiing trips.

Collier was a Wilmington native and Somerville resident who had worked at MIT since January 2012, MIT said.

Before that, he was a civilian employee of the Somerville Police Department, MIT said.

MIT Chief John DiFava says Collier was a dedicated officer, liked by his colleagues and the MIT community.

MIT President L. Rafael Reif said Collier's loss is "deeply painful."

Collier was found shot several times in his vehicle at about 10:30 p.m. Thursday.
